DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in FIG. 1, the present invention relates to an underwaterexercise equipment 200. The underwater exercise equipment 200 comprisesa lens 400, a gasket 500 and a buckle apparatus 100. The gasket 500 isdisposed on the periphery of the lens 400. The buckle apparatus 100 isdisposed at two opposite edges of the lens 400 and used to adjust thelength of an adjust belt 300.

Please refer to FIG. 2, the buckle apparatus 100 comprises a base 110, abuckle 120 and at least one pressing portion 130. The base 100 extendsfrom a first end 410 of the lens 400 and is integrally formed with thelens 400, and the base 110 has a rotation axis 112 where the adjust belt300 can bypass. The buckle 120 is pivotably disposed on the base 110.The pressing portion 130 extends from a second end 420 of the lens 400and is integrally formed with the lens 400, and the at least onepressing portion 130 is disposed adjacent the buckle 120. The aforesaidfirst end 410 and the second end 420 are different ends of the same sideof the lens 400.

In this way, when the adjust belt 300 bypasses the rotation axis 112,the buckle 120 can achieve the purpose of fastening the adjust belt 300by clasping the adjust belt 300 via the initial installment statusthereof when no external force is applied. When the length of the adjustbelt 300 is to be lengthened or reduced, the adjust belt 300 can bereleased from the buckle 120 by pushing the pressing portion 130.

In detail, in a first embodiment as shown in FIG. 2, the at least onepressing portion 130 of the buckle apparatus 100 is a single pressingportion 130, the pressing portion 130 extends from the second end 420 ofthe lens 400 and is integrally formed with the lens 400. By theaforesaid arrangement, when the user pushes the pressing portion 130,the pressing portion 130 pushes the buckle 120 from bottom to top fromthe lateral side of the buckle 120 (i.e., in the Z direction) so thatthe buckle 120 is opened for a particular angle along the Y direction,thereby releasing the adjust belt 300 from the buckle 120 to completethe adjustment of the adjust belt 300.

The aforesaid description that the base 110 and the pressing portion 130all extend from the lens 400 and are integrally formed therewith mayalso be interpreted as that: the lens 400 has two extending portions(i.e., a first end 410 and a second end 420), one of the two extendingportions forms the base 110, the other one of the two extending portionsforms the pressing portion 130, and the two extending portions are allintegrally formed with the lens 400.

In the embodiment of FIG. 2, a tenon 122 of the buckle 120 is insertedinto a groove 114 of the base 110 so as to achieve the purpose ofenabling the buckle 120 to pivot relative to the base 110 for aparticular angle, but it is not limited thereto. In other words, thebuckle 120 may also be pivotably disposed on the base 110 in other waysso that the buckle 120 clasps the adjust belt 300 when no external forceis applied, and the adjust belt 300 is released when the pressingportion 130 is pushed.

Moreover, under the premise that the single pressing portion 130disclosed in the first embodiment is formed integrally with the lens400, the pressing portion 130 not only can extend to the lower side ofthe base 110, those of ordinary skill in the art may also make changesreadily, e.g., enable the pressing portion 130 to extend to an upperside of the base 110, or enable the pressing portion 130 to extend toanother side (i.e., an inner side of the base 110) opposite to thebuckle 120 depending on other design requirements or the like, and thusthe purpose of clasping the adjust belt 300 when no external force isapplied, pushing the buckle 120 by pushing the pressing portion 130 andthereby releasing the adjust belt 300 from the buckle 120 can also beachieved.

In a second embodiment of FIG. 3, components of the buckle apparatus 100such as the base 100, the buckle 120 and the pressing portion 130 aswell as the spatial arrangement between these components are generallythe same as those described in the first embodiment of FIG. 2, and thuswill not be further described herein. The only difference between thesecond embodiment of FIG. 3 and the first embodiment of FIG. 2 lies inthat: the rotation axis 112 of the second embodiment of FIG. 3 is notintegrally formed with the base 110. Therefore, when the rotation axis112 of the second embodiment of FIG. 3 is damaged, only the damagedrotation axis 112 needs to be taken down and replaced with a newrotation axis 112 instead of changing the whole base 110.

In a third embodiment of FIG. 4, components of the buckle apparatus 100such as the base 110, the buckle 120 and the pressing portion 130 aswell as the spatial arrangement between these components are alsogenerally the same as those described in the first embodiment of FIG. 2,and thus will not be further described herein. The only differencebetween the third embodiment of FIG. 4 and the first embodiment of FIG.2 lies in that: the third embodiment of FIG. 4 has two pressing portions130.

In detail, as shown in FIG. 4, when the at least one pressing portion130 of the buckle apparatus 100 is two pressing portions 130, the secondend 420 of the lens 400 may be divided into two secondary ends 420′ thatare disposed on the upper side and the lower side of the first end 410respectively. In this way, the two pressing portions 130 may be extendedfrom the secondary end 420′ at the upper side and the secondary ends420′ at the lower side to an upper end and a lower end of the base 110respectively. In this way, when the user applies an external force topush the pressing portions 130, the pressing portions 130 can push thebuckle 120 laterally from the upper side and the lower side of thebuckle 120 so that the buckle 120 is opened for a particular angle alongthe Y direction, thereby releasing the adjust belt 300 from the buckle120.

Additionally, in a preferred embodiment of the present invention, thebase 110 is made of a material selected from the group consisting ofpolycarbonate (PC), acrylonitrile butadiene styrene (ABS), polypropylene(PP), Cellulose Acetate (CA), Triacetate Cellulose (TAC) andcombinations thereof. Moreover, the Shore hardness of the buckleapparatus 100 and the underwater exercise equipment 200 is between D50to D80, and the Rockwell hardness thereof is between 90 to 150.

According to the above descriptions, the base 110 and the pressingportion 130 of the buckle apparatus 100 of the present invention allextend from the lens 400 and integrally formed with the lens 400. Thus,in the case of the first and the third embodiments, only the buckle 120needs to be assembled; and in the case of the second embodiment, onlythe buckle 120 and the rotation axis 112 need to be assembled.Therefore, as compared to the prior art, the buckle apparatus of thepresent invention indeed can effectively reduce the number of componentsto reduce the production cost, can be assembled conveniently to improvethe production speed during the manufacturing, and is smooth and simplein the appearance so as to increase the desire of buying of the user.
